Here are some more information for Lens Student:
A professional HD video camera is one of the must-haves of avid filmmakers. These video cameras are the hottest item when it comes to the film-making or documentation industry. There are so many high definition camcorders in the market that are available but only a few are noteworthy. These are the:
- Canon XH-A1 HDV Camcorder, - Sony HDR-FX7 Camcorder, - JVC GYHD110U MiniDV Camcorder, and; - Panasonic AG-HVX200.
The Canon XH-A1 HDV Camcorder
This miniature version of the Canon XL H1 performs like its big brother, the Canon XLH1DV. It has a low light performance which is a good feature for a professional HD video camera. However, being small has its drawbacks. It has no lens interchangeability unlike the bigger version. Customers are somewhat skeptical with the 30F and 24F frame rates too but some are finding it easy to adjust to. It also has a bad eyecup design and is quite heavy for a video camera. Nevertheless, this is still good for ENGs, budget documentarians, student filmmakers.
The Sony HDR-FX7 Camcorder
The Sony FX7 is labeled as the company's consumer camcorder. It has a clear VID CMOS sensors which make a fantastic impression in bright light. Under low light conditions, the performance disappointingly falls to pieces. It can however, omit XLR inputs and external audio level controls.
The JVC GYHD110U MiniDV Camcorder
This camcorder's lens interchangeability and size is almost the same with the Canon XH-A1 HDV. It has a standard Fujinon 16x ProHD Lens. It comes with true progressive video at 720p but it doesn't offer interlaced video recording options. The resolution is close to XH A1's resolution. If you are the type of shooter who prefers larger camcorders and lens flexibility, buy a JVC GYHD110U.
Panasonic AG-HVX200
This camcorder uses the proprietary P2 tapeless recording system. It is able to record DVCPRO video DV tapes, but can only be recorded using Panasonic's solid state P2 memory cards or an external DTE drive like non-tape media. By using the P2 Cards, you can record non-stop and reduce the tape transfer time because of the camcorders 2 swappable P2 slots. The camcorder relies on pixel shifting to raise the resolution of its 3 1/3 " CCDs from 500k gross pixel count to a high definition resolution.
Different filmmakers have different professional HD video camera needs. The decision is yours to make. It is up to the aspiring filmmaker to decide which camera will cater to his or her needs more. Is the camera worth the price? That is for the filmmaker to judge.

Here is the Contact Lens With Electronic Circuits
This time it is the animation turning to reality! Yes its true, the engineers at University of Washington have been successful in creating a flexible, biologically safe contact lens with an imprinted electronic circuit and lights by installing manufacturing techniques at microscopic scales. They have been designed to create virtual cross hairs in order to aid visually impaired people. They can be even used for holographic driving control panels and the way to surf the web on the go. These are just some of the usage of this lens as scientist argue that there are many applications that people will realize only after using these lenses.
Babab Parviz, assistant professor of electrical engineering at UW claims that through these lenses one can see what the display is generating superimposed on the world outside. The professor is also of the opine that this small initiative is a big leap towards a promising goal. The main authors and co authors of this research are Harvey Ho, a former graduate student of Parviz's now working at Sandia National Laboratories in Livermore, Calif and Ehsan Saeedi and Samuel Kim. This lens was presented at the Institute of Electrical and Electronics Engineers' international conference on Micro Electro Mechanical Systems held on January 18th 2009.
The lens can have wide range of applications
The engineers who were involved in the research are of the view that the uses of these lenses can be very wide in scope. They will not only act instrumental for drivers and pilots to see a vehicles speed projected onto the windshield but the gaming industry too will benefit from it as these lenses will enable the user to transpire virtually in the animated world.
This lens were tested on rabbits for 20 minutes and they showed no inauspicious effect. Thanks to the prototype device that contains an electric circuit as well as red light-emitting diodes for a display, though it does not yet light up. The gadget is so human friendly that one will not be able to realize that he or she is wearing it. Second of all, its easy enough to pop in and out as well.
The engineers confessed that building a gadget like this is not an easy task as unlike the rest of the body our eyes are very sensitive. The methodology of manufacturing this lens involved inorganic materials, scorching temperatures and toxic chemicals. To manufacture them, the engineers built the circuits from layers of metal only a few nanometers thick, about one thousandth the width of a human hair, and constructed light-emitting diodes that are one third of a millimeter across. They sprinkled grayish powder of electric components on a flexible plastic sheet and used the technique called self assembly to create these tiny magical marvels.
This lens is designed in a way not to affect a persons vision and can also be used as a corrective lens. The professor also pinned hope on the possibility of a wireless communication to and from the lens. According to Parviz, "A full-fledged display won't be available for a while, but a version that has a basic display with just a few pixels could be operational "fairly quickly."

What is the best everyday lens for Nikon D200?
My main concern is sharpness, so I guess I'm looking for shutter speed? I'm new to photography (photojournalism student) and I just got a Nikon D200. I have an 18-55mm kit lens and a 55-200 VR zoom, but I'm looking to buy one more for now that will take really SHARP shots even if the subject is moving. Preferably inside, as well, without flash.
Suggestions?
The Nikon AF-S 17-55mm f/2.8 G IF-ED DX Zoom Lens is your very best option. It has a fast, fixed aperture for low light work and it is very sharp! The other lens you should look at is the Nikon AF-S 70-200mm f/2.8G IF-ED VR Nikkor Telephoto Zoom Lens. It is again, a fast fixed aperture lens of the highest quality and will produce excellent sharp images!
Those two pieces of glass will run you in the $3000 range, but they are the very best in their range.
I use the 17-55 for weddings, portraits, landscapes and a general walk around lens. It spends more time on my body than any other lens. The 70-200 is a close second. I photograph a lot of sports and aircraft in flight. This lens is incredibly sharp at f4 and the autofocus is fast and accurate. I have used both of these lenses on a D200 with no complaints at all.
Good luck with your decision!
